nauty-copyg — convert format and select subset

Synopsis

copyg [-gszfp#:#qhx] [infile [outfile]]

Description

Copy a file of graphs with possible format conversion.
-g
Use graph6 format for output
-s
Use sparse6 format for output
-z
Use digraph6 format for output
-i

Use incremental sparse6 format for output

In the absence of -g, -s, -z or -i, the format depends on the header or, if none, the first input line. As an exception, digraphs are always written in digraph6.

-p# -p#:#

Specify range of input lines (first is 1) This can fail if the input has incremental lines. -f With -p, assume input lines of fixed length

(ignored if header or first line has sparse6 format).

-I# Have at most this number of incremental steps

in a row.
Implies -i.
-h
Write a header.
-x

Don't write a header.

In the absence of -h and -x, a header is written if there is one in the input.

-q
Suppress auxiliary output.
